Hi Fresh reinstall WIn10Pro home office pc -- want to ensure OS (WIn10pro x64) doesn't alter behind the scenes.

Want to prevent MScopilot or other rogue AI is not hiding changes unclear/unknown to user. Pc Admins and also PC std users

Have FF v140 syncing to a Msoutlook userid and have donated under that id. The donwloaded install was done via a private window as Edge had to be used.

New installs of everything. Full virus scans etc. latest updates. But still seems like MS trying to prevent using FF unaltered.

Is it best to set up a profile and then disconnect sync; then reset FF periodically and turn sync back on? Some IT people said they've done that for a while.

Are local windows users not supposed to be able to save FF settings?

Are we inviting in MS by syncing and/or donating to Mozilla / Firefox with outlook.com addresses?

Thanks.

Firefox 139.0.4. version is also not good! Uploading videos to Youtube does not work with it! It does not move from zero percent! As I wrote earlier, the problem started with version 138.0.4. and is still ongoing! Uploading videos works with other browsers! I am waiting for the problem to be solved! If I wrote my letter in the wrong place, please forward it to the authorities! At the moment I could write a letter here, I can't really find a topic where this would be discussed! My OS Win10 64 bit. Thank you!

Sir/ Madam,

    It is delight to use and experience with Firefox Mozilla browser. I request to  make Firefox Mozilla as main.

After updating Firefox yesterday, when I use the search bar, switching between my custom search engines can only be done via clicking on a drop down menu at the left end of the search bar and selecting one with the mouse cursor. Previously, I could select my preferred search engine by using the up or down keys to cycle through them while typing a search, then hitting enter when the one I wanted was highlighted. Having to switch from keyboard to mousepad while typing a search is really annoying, I found the old way much more convenient. Is there a way to revert this, and put the search engines back at the bottom of the search suggestions, where I can access them with arrow keys?

Also, when I search now, the search stays in the search bar instead of changing to a URL, and I have to click a little internet globe icon at the right end of the bar for it to show the URL. This is also kind of annoying. Is there a way to turn this off, and just set it to show the URL every time?

YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

Since the last update Firefox sends the processor load through the roof. Both on desktop and on Android. For the first time since like version 7 I'm a bit disappointed.

What's up with this?

I own a website that has chat rooms for each of my advisors. As of 2 days ago they are all having issues. I have them login with Firefox but now asking them to use Google Chrome...............low and behold it works

Whats the issue as i believe it started with the latest Firefox update

Thanks so much

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

Hello.

I use Firefox on an computer with Ubuntu, (installed as snap) and have noticed that since the update to version 140 (specifically, version 140.0 canonical-002-1.0), closing a tab causes a noticeable delay : that is, upon any action that would close a tab (clicking on the cross, pressing CTRL+w, or middle clicking), there is a delay of about 200 to 300 ms before the tab is actually closed.

However, during this delay, the window still responds to inputs, leading to rather annoying situations. For example, during regular usage, I usually open a great number of tabs. When I am done with browsing, I close them, by repeatedly clicking the cross button on the tabs. It used to be that the tab under the cursor would immediately close, then the next tab would slide under the cursor, and I would click again to close that one, etc.

But now, when clicking the cross button, the tab is not closed, and when I click again after a small delay (because of muscle memory), the tab is still there. This cause the two single clicks to be treated as a single double-click, which for some reason puts the window in full-screen mode (but only with the snap version; I'm not sure what's going on here).

When using CTRL+w when closing tabs, the delay is still there, but the inputs are correctly handled. If I press CTRL+w three times at the usual rate, I can see the three key presses, then nothing happens for a few instants, then the three tabs close at the same time (i.e. the delay is from input to tab close, not from tab close to other tab close).

This behaviour is completely absent on Firefox (also version 140) on my windows computer.

This delay does not appear when creating tabs, and it does not occur either when closing the window or when closing the last tab in the window (leading to an amusing situation where shutting down Firefox is actually faster then closing a tab). These operation keep going at their previous speed, immeasurably fast to the human eye.

Navigation does not appear to be meaningfully slower than before the update, and the CPU/memory usage is very reasonable.

Curiously, this appears to be a fixed delay. Closing an empty tab takes the same time as closing a very busy one. Closing a tab when there are five takes the same time as closing a tab when there are thirty.

This issue makes browsing feel incredibly sluggish.

Is there a solution for this problem ?

Edit 1 : I have tried to run Firefox in troubleshoot mode, but there was no difference in behaviour. Edit 2 : Fixed typo. Edit 3 : Added exact version. I also tried to refresh Firefox, but the issue remained. Edit 4 : The problem is still present in version 140.0.1 canonical-002-1.0. Edit 5 : The problem is still present in version 140.0.2 canonical-002-1.0.

How can one search for bookmark-folders? (not a a bookmark contained by a folder) I have my bookmarks sorted in a tree-like structure via bookmark folders. It would be essential to me to be able to search for the folder in a search bar (like in the bookmark sidebar), since I have many folders/sub-folders.
